Rend Lake College will host a one-and-a-half day Wine Chemistry Workshop featuring Dr. Barry Gump on Friday and Saturday, April 16 and 17, 2010 in Ina. This fully hands-on workshop, offered through the Viticulture Enology Science and Technology Alliance (VESTA), will cover the following chemistry tests critical to quality wine production:
" Soluble Solids: Determination by Refractometry
" Soluble Solids: Sugar per Berry by Refractometry
" Sugars: Reducing Sugar by Visual Rapid Estimation
" Hydrogen Ion Concentration: pH Meter Measurement
" Titratable Acidity: Titrametric Procedure Production Modification
" Titratable Acid: AOCAC (Titrametric) Procedure
" Ethanol: Three Methods of Determination
" Malolactic Fermentation: Monitoring by Paper Chromatography
" Nitrogen: Estimate of FAN by Formol Titration
" Sulfur Dioxide: Aeration Oxidation Distillation and Titration Procedure
" Acetic Acid: Steam Distillation of Volatile Acid Using Cash or Markham Still
Dr. Gump is a Professor of Analytical Chemistry & Enology at Florida International University and the co-author of "Wine Analysis and Production." Dr. Gump has a long association with the wine industry, conducting research in analytical methodology applied to enology and viticulture. He is a technical editor for the Journal of the American Society for Enology and Viticulture, and a professional wine judge.
The cost of the workshop is $150, which includes lunch on the first day. There is a discount for groups of two or more from the same winery. Class size is limited to 24 participants.
